Many people like to claim that we, as Americans, are to dumb to understand the Metric system. Thus being the reason we don't use it. However, I would like to point out the fact that we are, I think, the only country that actually use both systems. If you look at anything medical, it is in Metric numbers. We also purchase many things using the Metric system. Why do we use both systems here in America? So the rest of the world doesn't have to try to convert(much to hard for them.) So in conclusion, we as Americans, are far more superior to anyone else, and much more intelligent. [/pointless rant]

again, it's an American thinking they're better than everyone or the only ones that do something. Don't say America is the only country using both systems, many other countries do too, usually for height of a person in feet.

Although we do use the metric system in the UK we still use miles and our cars (although we're right hand drive) display MPH!
I still weigh the fish I catch in lbs and ounces, yet I buy my drugs by the gram!!

Woah... slow down here. The rest of the world got itself civilised way before The US even existed. This proves the US aren't superior to other countries. The US isn't the only country to use both systems, and neither system is applied to currency.

way to go to the "you're a stupid, young country" argument. Remember we didn't come out of the wilds of North America, we come from Europe and the rest of the "civilized world". So, in effect, we were civilized at the same time, just that the US formed its government later.

btw, we've saved you're asses a couple times so we have every damn right to use whatever system we want. Even if it doesn't make any sense whatsoever.

Imperial units or the imperial system is a system of units, first defined in the British Weights and Measures Act of 1824, later refined (until 1959) and reduced. The system came into official use across the British Empire. By the late 20th century all nations of the former empire had officially adopted the metric system as their main system of measurement.

The imperial system is one of many systems of English or foot-pound-second units, so named because of the base units of length, mass and time. Although most of the units are defined in more than one system, some subsidiary units were used to a much greater extent, or for different purposes, in one area rather than the other. The distinctions between these systems are often not drawn precisely.

One such system is the US customary system, which is historically derived from units which were in use in England at the time of settlement. Because the United States was already independent at the time, these units were unaffected by the introduction of the imperial system. Units of length and area are mostly shared between the imperial and US systems, albeit being partially and temporally defined differently. Capacity measures differ the most due to the introduction of the imperial gallon and the unification of wet and dry measures. The avoirdupois system applies only to weights; it has a long designation and a short designation for the hundredweight and ton.

Another distinction to be noted is that between these systems and older British/English units/systems or newer additions. The term imperial should not be applied to English units that were outlawed in Weights and Measures Act of 1824 or earlier, or which had fallen out of use by that time, nor to post-imperial inventions such as the slug or poundal.

I'm not saying the US is a stupid, young country, it isn't. I'm simply saying that it doesn't have any right to have a go at other countries that are just as sophisticated, and use the same sodding measurement systems.
(I don't really know why we're arguing either)

i think it depends what line of work you are in for example the metric system is alot better in engineering and fabrication but imperial is better in things like pipe fitting where the tolerances arnt as tight in most cases
